Petty and company are legit, from gear , to album art, to recording quality , vintage guitars, you name it. Petty on balance over 45 years may have had the best career of any American Rock musician outside of Elvis...His own Catalog aside, the collaborations range from Beatles to Johnny Cash. Dylan, Leon Russell, Jeff Lynne, Dave Stewart, and Del Shannon , Orbison, Carl Perkins, Dave Grohl..etc. then his late career resurgence with Mojo, and Hipnotic Eye..and dabblings with Mudcrutch..Stevie Nicks. Etc. etc.
